Answer 1

Preorder Traversal is the subject of this collection of Data Structure Multiple Choice Questions & Answers (MCQs).

1.The pre-order traversal for the tree is given below.

b) 2, 7, 5, 2, 6, 9, 5, 11, 4

c) 2, 5, 11, 6, 7, 4, 9, 5, 2

d) 2, 7, 5, 6, 11, 2, 5, 4, 9

What is preorder traversing?

• However, there are numerous ways to navigate around the data in a hierarchical data structure like a tree. In preorder traversal, the root node is visited first, followed by the left subtree, and finally the right subtree. Root left, and right are representations of the preorder traversal process.

• A binary tree traversal method called preorder traversal visits the root node first, followed by the left subtree and the right subtree. We can traverse binary trees in a variety of ways due to their hierarchical nature, unlike arrays and linked lists, which are linear data structures.
